Sure, but that's exactly where I'm in disagreement. The change into
Napoleon is a difference in kind, not degree, as one would have to
pass through non-functional brain structures in order to change from me to
him. Whereas to change from me to me as I was twenty years ago can be
achieved by passing through functional brain structures (all the
instances of me over the last twenty years).
